Seasonal Variation in Three Leguminous Tree Seedlings Associated with AM Fungi

Three important leguminous plants Tamarindus indica L., Dalbergia sisso Roxb., Cassia nodosa Roxb., their ischolar_mains and soil samples were screened for their AM fungal association. Percentage of ischolar_main colonization and spore number of these plants were co related to each other. Higher spore number was recorded in Cassia nodusa Ham., during December and April compared to Tamarindus indica L., Dalbergia sisso Roxb in soil depth between 16-24 cm. On contrast to this per cent ischolar_main colonization significantly increased during April in Dalbergia sisso Roxb. , Tamarindus indica L., followed by Cassia nodosa Ham. The results revealed that both ischolar_main colonization sporulation declined from September to April in the examined tree species.
